GRAIN SHOCKER.

Application led June 22,

T all whom t may concern.' i

Be it known that I, Crier Mii R. Banni', a citizen oi' the United States, residing at Chicago, in the county oi Cook and State of Illinois, have invented certain new and useful Iiiiproveiireiits in Grain Sliockers, oi which the following is a specification VMy invention relates to a grain shocker and more particularly to an improved construction in which the base or butt ot the shock is spread in all directions with respect to the body portion of the shock in such a manner that the proper ventilation and airing can be had'so as to insure complete curing or drying out of the grain in thebound shock.

One of the objects of the present invention is to provide a simple and efficient butt spreading mechanism which will insure the building of stable shocks in the iield.

A further object of the device is to provide a novel construction oit butt spreading mechanism which will engage the butt of the shock at points a considerable distance trom the plane of the base ot' the 'shock when the shock is in its normal piosti'ate position and swing outwardly and downwardly with respect to the plane ott the base ot the shock when the shock is set upright on the ground. i

A further objectot` 'the invention is to provide, a novel construction of' pivotally mounting the butt spreading mechanism in such a manner that the butt spreading tines more from their normal 'shock building position, which is the vertical position, to the shock discharging position. In this latter position they assume a diver-ging or butt spreading position with respect to the shocking machine.

These and other objects are `attained by providing an iniproved butt spreading mechanism which cci-operates with the shock discharging mechanism to lengiug'e the butts of all the sheaves in the shock in a manner to spread the butts ot' the shock as the shock is being discharged upon the ground by the discharging mechanism;

The invention hereinafter described and claimed is an improvement over the constructions described and claimed in certain other eoependiiig applications.

ln order to disclose my invention have illustrated the preferred embodiment of the 1923. Serial No. 647,065.

same as shown in the accompanying drawings.

In these drawings Fig. 1 is a. top plan view of a shocking `machine showing my improved butt spreading mechanism embodied therein Fig. 2 is a side elevational view of the shocking machine shown in Fig. 1 showing the butt spreading mechanism in its vertical position in full lines and in its butt spreading or horizontal position in dotted lines;

Fig. 3 is a rear elevational view showing lthe manner in which my improved butt spreading mechanism is mounted on `the discharging mechanism of the shocker;

Fig. 4 is an enlarged top plan view showing in detail, the manner in which the tine's are pivotally connected to the discharging mechanism of the shocker, and

Fig. 5 is an enlarged detail view `partly in section 'showing the latch mechanism for locking the butt spreading mechanism to the shock discharging mechanism.

The shocker shown is of the general type described and claimed in my U. S. Patents Nos. 1,231,195 of June 26, 1917, and 1,292,- 922 of February 11, 1919, a rearwardly swinging sheaf delivery member or tork 11 being used, which is carried on a shocker frame and movable by a pitman connection 11 about an axis on a shaft 12 from its 'sheaf receiving position or the posi tion shown in Fig. 2, wherein it restsbeneath thev deckof the grain binder, not shown, to its sheaf delivering position, wherein it delivers sheaves in prostrate position in an upwardly and rearwardly movable sliock receptacle 13 carried by the rear end of the shocker frame. Also after 'the manner described in my U; S. Letters Patents Nos. 1,231,195 of June 26, 1917, and 1,242,112 of October 2, 1917, when enough 'sheaves have been delivered to the shock receptacle 13 to build a shock of a predetermined size, a needle 14. and knot-ter mechanism 15 are thrown into operation to coinpress and bind the shock, and "at the com* pletion of the compression and binding operation through the rotation ot a knetter shaft 16 the shock receptacle 13 is moved .upwardly and rearwardly to 'deposite the shock in an upright position on the ground.

'The fark llfytogether with all @he iopera Al l) tive mechanism upon the present shocker are driven from a longitudinally power driven shaft 17, the forward end of which is connected to a second shaft of eXtensible and flexible character deriving its power from the crank shaft of 'the grain binder to which the shocker is attached, Both ends of the shaft 17 are journalled in a main frame bearing box 18 which is 'secured to the main frame by depending ears 19 formed integrally with the bearing box 18 and secured to the main frame by means of bolts.

Also, as described in my Patent No. `1,231,195 of June 26, 1917 in a manner cominon to all shockers of this type, a continuously operating clutch ineniber 20 is secured to the rear end of the shaft 1T by a pin 21. Engageable with the continuously operating clutch member 2O and adapted to be driven thereby, is an intermittently operated clutch member 22, which is normally controlled by a pawl, not shown. Formed integrally with the intermittently operated clutch member 22 is a drive sprocket 23. Gea-red to the drive sprocket 23 and operatively driven thereby by means of a driving chain 24 is a sprocket 25 secured to the knetter shaft 16 5by a key 26. Through the mechanism just described, it will be understood that the knetter mechanism is operated to bind the 'shocks through the power derived from the harvester when the number of she-aves in the shock receptacle has reached a predetermined height in said receptacle.

Secured to the rear end of the knetter 'shaft 16 is a crank 2'?. The free end of the crank V27 is provided with Va stud I28 which haspiv'otally secured thereto a` knuckle joint and pitinan connection 29. The vloi'vrer end of vthe pitinan connection 29 is pivotally -secured by a similar knuckle joint 30 journal led on a stud 31 afiied lto a crank 32 journalled on the grainward end of a crank shaft 33, which, in turn, is journalle'd 'on a 'supplemental inain 'frame' member 10 by means of bearingbrackets 34 secured to said fra-ine member. Secured to the grainwa'rd end of the crank shaft 3 adjacent the crank 32 is a second crank The crank 35 is adapted to be engaged by a Gravity actuated pawl 36 pivoted at 3'? to the crank 32. VEhe stubbl-eward end of the crank shaft 33 is provided with a forwardly extending arm 38 positioned beneath and extending para-llel with the shock receptacle 13 wh-en the saine is in its normal bundle or sheaf receiving position. The free end of the crank 38 is provided with roller 39, which is adapted to engage the lower or bottom side of the shock receptacle 13 as the same is actuated about its pivot in the normal oper-zw tion of setting a shock. Secured to the opposite sides of the rearwardly ckt-ending main frame 1G is a transversely extend-ing pipe or shaft 40. Tilta-bly mounted by means of hinged brackets 41 on the pipe 40 ina manner to be swung upwardly and rea-rwardly with respect .thereto is the shock receptacle 13.

My improved mechanism for spreading the sheaves in t-he shock set by the shock receptacle during the setting of the shock and also during the withdrawal of the shocker vfrom the shock after the shock has been set on thel ground will next be described.

Securely liked to the pipe 40 and positioned on the opposite ends thereof, are hinged brackets 42 which are adapted to pi'votally support a transversely extending tine shaft 43. The shaft 43 is provided, on its stubb-leward end, with a curved portion 44. rPhe upper or free end of this curved portion 44 of the shaft 43 has connected therewith an extension spring 45. The forward end of the extension spring isconnected to the main frame 10 of the shocker. The extension spring 45 returns the shaft 43 together with the tines, hereinafter described, to their lhome or normal ver-tical position. Positioned on the opposite sides of the 4medial line of the shocker, and pivoted to the shaft 43 -at 46, are two sets of butt spreading tines 47. These tines are `of a crank-like construction and comprise a normally vertically extending portion 48, an otfset portion 49 and a butt engaging p0rtion 50. The butt engaging portion is angled slightly with respect to the pivoted or vertically extending portion 43, asvclearly shown in Fig. 1. Thus, it willv be appreciated that when the oppositely disposed sets of tines are in their normal vertical position (Fig. 3) they are disposed -in parallel relationship with respect to each other and that 'when they are in their horizontal or ybutt spreading position 1) they assume. a divergjing position. ln order to strengthen the pivotal connections of the tines 4T with the shaft 43, I have provided spacer brackets 51 secured to the shaft 43 by means of bolts These brackets 52 are provided with apertures 53 in which the upper parts of the vertical portions 48 are vpliif'o'tally supported. T he tines are retained in their pivotal positions on the shaft 43 by Cotter pins 54. Each set of tines positioned on the opposite sides of the medial line vof the shocker is connected together by a tie bar 557 which in turn, is held vagainst displacement by a second bar 56 pivoted tothe tie bar 55 57 and pivoted to the bracket 51 at The tines are actuated to swing about their respective Apivots by a vpitnoan connection 59. The inner ends of the pitman connection 59 are pivotally connected adjacent the pivots 58 to bars 56. The outer ends. of the pitnian 59 are pivotally connected to brackets 60 secured to the pipe 40.

`Frein the construction just described, it will be seen that as the shock receptacle 13 is actuated or tilted upwardly and rearwardly in the operation of discharging the shock upon the ground, the butt spreading mechanism, which includes the tines 47, is moved iu unison with the receptacle 31 and during such movement the tines 47 are swung about their pivots i6 from their normal vertical and parallel positions shown in Fig. 3 to their horizontal diverging positions as shown in Fig. 1. It will also be not-ed thatwhen the tines are in their normal or vertical positions they extend forwardly in advance ot' their pivots and that as the shock receptacle together with the tines are swungl to discharge the shock, the tines are then` swung rearwardly with respect to their pivots to suoli an extent that the upper portions ot the respective tines assume a position in which a plane extending transversely and through the pivot portions 4S of the tines will almost include these portions 50. (See Figs. 2 and 4f.)

The butt spreading mechanism, including the shaft 43 and the tines 47 is normally locked in its vertical position to the shock receptacle 13 by alatch 6l pivoted to the receptacle 13 by means of a pin (S2 pivotally connected to the bracket 62 secured to the receptacle 13.` The free endot the latch 6i is pressed downwardly by `a compression spring 61 in a manner to engage a pawl 63 secure-d tothe shaft 43 by means of clamping bolts 64. The latch is actuated to automatically unlock, by means of a rearwardly projecting portion G3 engaging the underside oit the latch G1, the butt spreading mechaniem from the receptacle 13 so that the receptacle 13 may return to its normal sheat receiving position independently of the butt spreading mechanism.` The receptacle 13 is returned to its normal shea receiving posiion by means of an extension spring (i4: connected at its forward end to the shocker trame andat its rearward end .to the receptacle 13 by means of a chain G5. After the shock has been set upc-n the ground and the tines i7 have been withdrawn from beneath the shock, the extension spring 45, connected between the trame 10 and the curved portion 4st ot the shaft 43, returns the `tines 47 to their home or vertical position, as shown in Figs. i2 and 3. y

In the operation of my improved shock mechanism it will of course, be understood that the shock is builtprostrate in the receptacle 13 by means of themsheaf delivery member 11 delivering or conveying the sheaves from the binder deck of the harvester to the shear receptacle. lVhen the sheaves in the shock receptacle have reached a predete mined height or bulk, the intermittently operating clutch member Q0 is tripped, thus connecting this .Gllltlll ,member 2.2 with. the

continuously operating clutch member 20. Through this mechanism the knetter shaft 16 is driven by the sprockets 23, 25 and chain 24 and the crank 27 swung' upwardly, thereby elevating the crank 32 until the gravity actuated pawl 3G drops by its own weight and engages the second crank 35. Then upon the downward movement ot the crank 27, through the pitman connections 2l)V and the crank 3Q, the second crank swung' clockwise, swinging the arm 33 with the roller upwardly and rearwardly. rlhis upward and rearward movement of the crank arm 38 transmit-ted to the shock receptacle 13, setting the shock in a vertical po sition and swinging the butt tines t7 from the vertical position shown in 2 and 3 to the horizontal and divcrging position shown in Fig. 1. As these tines are swung from their vertical position to their horizontal position, they are swung laterally with respect to the dischargingmechanism .in a manner to spread the butts of the shock laterally with respect to thebody of the shock, as the shock is being set down upon the ground. It will also be noted that the tines L17 in their vertical position extend forwardly a considerable distance from the plane ot the base ot the shock and thereby firmly engage the shock in a manner to insure the proper spread of the shock as the same is being` set upon the ground. As previously described, the rines are actuated to swing about their respective pivots through the pitnian 5S) having their outer ends connected. to the brackets (it) on the opposite ends oi' the pipe el() and their inner ends pivotally connected to the bar 56, which in turn, is pivotally connected to the tie bar 5o, and as the lines i7 are actuated with their shatt t'il-.3 on the hinges from the vertical positifnito their horizontal position,v the tincs are .simultancously actu ated, to swing about their individual pivots fltl on the shaft 43.

From thc construction just described. it will be understood that as the shocker is withdrawn trom the shock with the tincs extending in diverging positions beneath the shock` and that as these tines are withdrawn in this position they have a tendency to dra or pull the sheaves in a longitudinal direction, `thereby longitudinally spreading the butts of the shock as well as laterally spreading the shock during` the withdrawal movement ot the rines trom beneath the shock.

lly reason ot this construction it will be readily seen that I have provided a very simple and very eiticient butt spreading mechanism and one which is adapted to adequately spread the butts oft the shock in such a manner as to insure the proper curing and drying out ot the grain in the shock. l
